Described are trimless door frames and energy absorbing door stops. The energy absorbing door stop allows for relative movement between the door stop and the surrounding door frame. The relative movement of the energy absorbing door stop helps to distribute and dissipate forces and vibrations from opening and closing a door, reducing the levels of force transferred into the surrounding wall. The reduction in forces applied to the wall allows for the elimination of heavy door framing and trim. Since door trim is no longer necessary, trimless door frames may be installed with a smooth appearance without cracks appearing in the surrounding wall due to stress or fatigue.

This application claims the benefit of U.S. Provisional Application Ser. No. 62/059,348 (“the '348 application”), filed on Oct. 3, 2014 and entitled “Trimless Door Frame.” The '348 application is hereby incorporated in its entirety by this reference.
Embodiments of the invention relate to door frames having energy absorbing door stops.
Door openings are generally surrounded about their perimeters or “trimmed” with heavy framing to absorb the forces and vibrations associated with repeatedly opening and closing a door mounted within a door opening. Heavy framing is necessary to withstand the day-to-day usage of a door without producing cracks in the surrounding wall due to stress or fatigue. However, door frames are visible and can prevent construction of doors with a smooth, modern appearance with no visible framing.
Aspects of the present disclosure relate to door frames that incorporate an energy absorbing door stop to distribute the forces and vibrations associated with opening and closing a door. The energy absorbing door stop helps to absorb and distribute the forces so that lower levels of force are transferred into the surrounding wall and thus obviates the need for a traditional door frame or trim. Decreased levels of force applied to the surrounding wall reduces the likelihood of cracking the surrounding wall due to stress or fatigue over many opening or closing cycles of the door.
The subject matter of embodiments of the present invention is described here with specificity to meet statutory requirements, but this description is not necessarily intended to limit the scope of the claims. The claimed subject matter may be embodied in other ways, may include different elements or steps, and may be used in conjunction with other existing or future technologies. This description should not be interpreted as implying any particular order or arrangement among or between various steps or elements except when the order of individual steps or arrangement of elements is explicitly described.
The described embodiments of the invention provide a trimless door frame assembly with an energy absorbing door stop. While the energy absorbing door stops are discussed for use with trimless door frames, they are by no means so limited. Rather, embodiments of the energy absorbing door stop may be used in any door including, but not limited to, fully framed or trimmed doors.
With reference to
The door frame 150, flush mount plate 200, floating door stop 250, and support plate 300 may be individual components that are assembled together as described below. In some embodiments, the door frame 150, flush mount plate 200, floating door stop 250, and/or support plate 300 may be combined and/or formed from a single piece of material. Any of the below described parts may be constructed from metals, such as aluminum, steel, or other alloys, polymers, composites, or any other material selected for its ease of manufacturing, cost, durability in use, and resistance to corrosion or other environmental conditions. Furthermore, the parts may be produced by machining, casting, stamping, extrusion, any other applicable forming method, or any combination thereof.
The frames sides 150a-c of door frame 150 may have different cross-sectional profiles tailored to their position within the door frame 150. However, in other embodiments, the frame sides 150a-c have the identical profile, an example of which is shown in
A floating door stop 250 may be positioned along the length of each frame side 150a-c and more particularly is positioned within the door stop recess 170 on each frame side 150a-c and retained therein via locator arms 280. The floating door stop 250 may include a door silencer 260 positioned within silencer recess 255 on the strike face 251 of the door stop frame 252. The door silencer 260 may be formed of a gasket material, such as a rubber or other elastomeric material. One exemplary gasket material for the door silencer is a thermoplastic vulcanizate (TPV) material. The door silencer 260 acts to seal the door 500 (not shown) against the floating door stop 250 and silences the door 500 as it closes against the floating door stop 250. The locator arms 280 may interact with the projections 175 of the door stop recess 170 to allow a loose-fit between the floating door stop 250 and door stop recess 170. As shown, the locator arms 280 have clearance around their ends to allow the floating door stop 250 to move laterally relative to the door stop recess 170. In certain embodiments, the locator arms 280 may have different end configurations to allow for additional degrees of freedom. For example, as shown in
The floating door stop 250 may also include one or more absorbers 270 positioned within or proximate to the door stop frame 252 and more particularly within the absorber recesses 265 of the door stop frame 252. The absorbers 270 may be a spring or a component made from rubber, an elastomer, cellular material, a polymer, a thermoplastic vulcanizate, or any other material selected for its ability to deflect, compress, or elongate and regain its shape to absorb and distribute forces. The absorbers 270 function to stabilize the floating door stop 250 in an aligned position within door stop recess 170 of a frame side 150a-c. When the floating door stop 250 encounters a force, such as when a door is closed against the strike face 251 of the door stop frame 252, the floating door stop 250 will be laterally displaced relative to the door stop recess 170, which compresses the absorber 270 distal the strike face 251 into a projection 175 of the door stop recess 170 such that the absorber 270 absorbs the energy of the door closure instead of the surrounding wall. More specifically, the motion and/or displacement of the floating door stop 250 distributes the impact of a door closure or other applied force over a larger amount of time as the absorber 270 deflects and extends the range of motion of the floating door stop 250. The impact energy applied through the floating door stop 250 extends over a larger time with a correspondingly lower peak force. Also, the internal friction and deflection of the absorber 270, along with any frictional losses due to the movement of the floating door stop 250 relative to any other parts of the frame side 150b, 150c may absorb and dissipate impact energy. The resulting force transferred through a trimless door frame assembly 100 to the studs 151b, 151c and wall or drywall 600 has a much lower peak magnitude relative to solidly mounted door stops. These lower peak forces greatly reduce the chances of cracking or fatigue, particularly of the wall or drywall 600 at or around the frame sides 150a-c and/or drywall screws 153, even through repeated cycles of opening and closing the door. While the floating door stop is shown equipped with two absorbers 270, it is certainly contemplated to use a single absorber 270 or more than two absorbers 270.
The floating door stop 250 may include any number of modifications or alterations to suit a particular application. For example, as shown in
In order to adjust or optimize the amount of force absorption for a particular application, the floating door stop 250 (with absorber(s) 270 and optional auxiliary absorbers 271) may take on different materials, geometries, or characteristics. For example, the absorbers 270 or auxiliary absorbers 271 may be hollow or solid, and may be made from any material that is suitable for its characteristics to compress, deflect, or elongate in response to an applied load over a large number of loading cycles. In some embodiments, the absorber 270 and/or auxiliary absorber 271 may be cast or otherwise molded in place within the absorber recesses 265 or between the floating door stop 250, locator arms 280, extensions 281, door stop recess 170, and/or projections 175. In certain embodiments, the absorbers 270 and/or auxiliary absorbers 271 may be asymmetrical so as to better adapt to differing levels of force applied in different directions. The absorber 270 and/or auxiliary absorber 271 may also be affixed or otherwise attached to the floating door stop 250, locator arms 280, extensions 281, door stop recess 170, and/or projections 175 by adhesives, directly molding the absorbers 270 and/or auxiliary absorbers 271 to a surface, or forming the absorbers 270 and/or auxiliary absorbers 271 in such a shape as to allow them to accept tensile loads between the floating door stop, locator arms, and/or extensions 281 and the door stop recess 170 and/or projections 175 in addition to compressive loads.

As shown in
Similarly, the strike plate frame side 150c may include a strike plate 340 affixed or otherwise attached to a support plate 300. The flush mount plates 200 may be cut to length and stacked in the hardware recess 160 of the strike plate frame side 150c along with the support plate 300 to vertically locate the support plate 300 and strike plate 340. In certain embodiments, the flush mount plates 200 may be notched, cut, or otherwise shaped to conform to the peripheral contours of a hinge 320, strike plate 340, or any other hardware that may be in contact with the flush mount plates 200.
Once the required components have been installed into individual frame sides 150a-c, the frame sides 150a-c may be connected with angle brackets 350 to form the door frame 150. The angle brackets 350 may be installed into assembly recesses 152 to connect the top frame side 150a with the hinge frame side 150b and strike plate frame side 150c on either side, respectively.
To further describe the operation and interaction of the flush mount plate 200, support plate 300, hinges 320, and/or strike plate 340, an exemplary installation method of strike plate frame side 150c is described. A first flush mount plate 200 is first inserted longitudinally into the hardware recess 160 (not shown) and slid along strike plate frame side 150c until the bottom of the flush mount plate 200 rests against the floor.
